Spring Breeze 1991

Yao Yuan kept his student ID card in hand, opened the driver's door and sat on one side.His 1.8-meter tall man follows his mother, and all the delicious food at home is close to him. He is tall and big.

Factory Manager Ye touched his nose and said to Driver Yu, "Xiao Yu, if he has other problems, I won't admit it."

"He's a college student, and he's familiar with this car, so it's fine." Driver Yu said, taking a deep puff on his cigarette.

Director Ye has seen Yao Yuan's student ID card, and has no doubts about Yao Yuan's college student status.As for whether Yao Yuan has this ability... He has already figured it out, and the county auto repair shop will not be responsible for any problems.Instead, he hoped that Yao Yuan would make other troubles, so that he could easily explain to his superiors.

Each had their own thoughts, but soon everyone's attention was on Yao Yuan.

But Yao Yuan checked the gear position and handbrake skillfully, stepped on the brake pedal with his right foot, and turned the key to start the ignition.The four-cylinder gasoline engine "squeezed" on, the noise was relatively loud, and the water temperature was very low, indicating that the car had been here for a long time.

This skillful movement makes people have to suspect that this kid is an old driver.

After the fire, the hydraulic pressure came up, and Yao Yuan felt that the brake pedal was going down faster than normal, which indicated that the brake system was abnormal.He stepped on the brakes repeatedly, the frequency changed from slow to fast, and then from fast to slow again, with no intention of stopping.

Master Liu frowned and said, "What's the use of stepping on like this?"

"Does this kid want to make a living?" A young worker joked as it was time for lunch.

However, Master Liu quickly noticed something was coming, showing a thoughtful look, but he still couldn't figure out what Yao Yuan was going to do.Generally speaking, for this kind of purely mechanical car, when adjusting the brakes, it is necessary to continuously step on the brake pedal, and another person adjusts the tightness of the brake wire according to the degree of stepping.

This is also a process of exhausting.

But this does not check out the failure of the braking system.

At this time, Liang Yaoming on the 212 jeep opened the door and wanted to get out of the car, and said fiercely, "I cheated you into the auto repair shop, I'll make you look good!"

When he saw the license plate number, he said in surprise, "Brother-in-law, look, it seems to be Director Li's car of the Farm Management Bureau! I'll go and have a look!"

"Don't get out of the car!" Liu Yitang grabbed Liang Yaoming, shook his head and said, "Let's have a look first."

Yao Yuan knew about his broken shoes, if Yao Yuan yelled in front of his brother-in-law, his mother and wife would eat him alive and strip him alive.

Liang Yaoming held back his anger, turned to think about his work, and said, "Brother-in-law, can the auto repair shop take me? My sugar factory job is not hot yet..."

"I said it's okay if there's no problem. Director Ye and I are... old friends."

……

Yao Yuanzu tried for a few minutes, then stared at the odometer for a long time, thinking about it.

After knowing it in his mind, he turned off the engine and got out of the car, and asked, "Master Yu, is there a phenomenon that the brakes don't work when driving on a bumpy road? Besides, there should be a lot of people in the car."

"That's right! That's right!" Driver Yu recalled it carefully, and then his eyes sparkled with excitement.

He hadn't told anyone about it, and he wasn't aware of this particular situation.

Smiling, Yao Yuan said, "But if you're driving on a flat road or with no load, there's no problem with the brakes, right?"

"That's right! Good guy! If I hadn't been driving this car all the time, I would have doubted that you had ever driven this car!" Driver Yu became even more excited.

Director Ye and the others were all dumbfounded, and the corners of Master Liu's mouth twitched even more.They judged the failure after a few simple tests, but they found nothing, so they judged it.

Yao Yuan asked again, "After buying this car, do you often run on mountain roads? And it's a dirt road with very bad road conditions."

"That's right, that's right, this car is really useful when it runs on bad roads!" Driver Yu said arrogantly.

Thinking about it too, there is no good way to go to the farm.Let alone farms, there are only a handful of paved roads in Nangang City today.

Yao Yuan nodded slightly, and said, "I know what's wrong, and I know where it went wrong."

"Great, great! Then, fix it quickly, Comrade Yao, I have to wash the car when I go back, and I will go to the airport tomorrow morning to pick up the Hong Kong businessman!" Driver Yu was so excited when he saw the blue sky through the clouds.

However, Yao Yuan shook his head and said, "It can't be repaired."

Ok?

Driver Yu was taken aback, his brows frowned, and suddenly he came back to his senses, "I know, I know, I...our unit will pay for the repair fee!"

He looked at Director Ye.

Director Ye also realized that this college student really knows how to repair. This must be a good thing. He also read Driver Yu's eyes and said quickly, "Comrade Xiao Yao, don't worry, the repair fee will be paid by our factory. Just... even if it is a work-study program with us, how about it?"

Yao Yuan shook his head and smiled, "Sorry, I really can't fix it."

Let's go.

Factory Manager Ye became anxious, and grabbed Yao Yuan's arm, "Comrade Xiao Yao, stay put, stay put, everything is negotiable, right? In this way, if you fix it, I'll give you 50 yuan!"

Generally, half a month's salary is less than half a month's salary.

Yao Yuan said helplessly, "Director Ye, it's not about the money, it's really impossible to fix it. I can tell you the cause of the fault and the faulty parts, and you can decide for yourself."

Factory Manager Ye was stunned for a moment, and quickly reacted, "That's not good, that's not good, it's the fault you found out, it's better for you to fix it."

He naturally thought that Yao Yuan was whetting his appetite.

Yao Yuan said, "It really can't be fixed."

"100 yuan!"

"It can't be fixed."

"five hundred!"

"It's not about the money..."

"1000 yuan!" Driver Yu shouted, as if he had made up his mind, he walked over step by step, and said firmly, "Xiao Yao, I'll give you 1000 yuan after you fix the car! How about it?"

Yao Yuan stopped talking, he was very embarrassed.

However, he wasn't trying to whet his appetite, but he really couldn't fix it!

This is a design defect of Mitsubishi's second-generation Pajero, and unless the manufacturer recalls it for repairs, the problem cannot be solved fundamentally.

The distance between the load-sensing valve at the rear of the car and the brake oil pipe of the rear axle is too small. When driving with multiple people on a bumpy road, the former will be pressed down and rub against the latter, so the brake oil pipe will become thinner and thinner until it ruptures.

The reason why the brake door incident did not break out until 2001 is because after a certain mileage, the brake oil pipe was worn out, and the problem broke out.

Just now Yao Yuan discovered that the odometer shows that the mileage is as high as 15 kilometers. Combined with the fact that the car has only been bought for more than a year, it is basically confirmed that it is a problem with the brake hose.

In his previous life, Yao Yuan studied the brake door incident that almost sent the Mitsubishi Pajero off the altar, and found an interesting phenomenon: the Pajero in the plain area had brake defects later than the Pajero used in the mountainous area.

This also indirectly proves that Mitsubishi did not fully consider the actual use of various terrains when designing. You know, this is an off-road vehicle.

Can Yao Yuan solve a problem that needs to be returned to the factory?

He was not sure, so he told them frankly that there was no way to repair it. Not only him, but no repair shop in China could completely solve this problem.So just now he has given up his plan to make this money.

However, when driver Yu offered a repair fee of 1000 yuan, he hesitated. This price is really hard to refuse.As a reborn person, Yao Yuan was aggrieved, and he wasn't even sure of earning a mere 1000 yuan.

Seeing that Yao Yuan was still hesitating, Driver Yu gritted his teeth and said, "I'll give you an extra two hundred! Xiao Yao, this is half a year's salary!"

In order not to be criticized, Director Ye also went all out and said, "Our repair shop will give you another 300 yuan, how about it? Xiao Yao?"

call……

Fifteen thousand.

Yao Yuan shook his head and said, "Okay!"

Just when everyone was relieved, Yao Yuan changed the subject and said, "But I'm ugly to say first, this fault is caused by a congenital defect of this car. I can't solve it completely for the time being. I can only guarantee that there will be no problem within two years."

"Two years? Enough is enough! This is enough!" Driver Yu, who thought Yao Yuan said that he could not guarantee the repair, was completely relieved.

No one noticed the "congenital defect" mentioned by Yao Yuan.

Driver Yu's eyes are only on the important reception task tomorrow, and Director Ye wholeheartedly wants to solve this matter smoothly and is praised by his superiors.Only Master Liu on the side listened attentively and thought seriously while looking at Yao Yuan.

It is actually very simple to solve the problem of brake failure, repair the damaged part of the brake oil pipe, or replace it, but this cannot fundamentally solve the problem. After a period of friction, the fault will also appear.

Yao Yuan carried the faults of his previous life—keep improving and solve problems.

Since people think that there is no problem with the two-year warranty, Yao Yuan will not elaborate further.

He wanted a flashlight and jumped down the ditch. Seeing this, Master Liu followed, lighting him up, with an open-minded attitude of learning.

Yao Yuan took a look and said with a smile, "I'm sorry, Master Liu. Look here, the load sensing device is here, and the oil pipe is here. It looks normal. This is because the vehicle is empty. If there are many people on it, plus the road surface Bumps, the load sensor is depressed... You can see that the brake oil pipe is damaged and leaking oil."

He touched it with his hand, and found that the brake oil pipe was severely worn, and a small crack appeared, and oil was slowly leaking out.

Master Liu's face was flushed, and the oil and dust mixed together covered the damaged area. At first glance, it was no different from normal, and this location was very hidden. If it was not for sure that there was a problem with the brake hose, it would be really difficult to find out.

"How to solve it? Is it packaged or soldered? We don't have spare parts." Master Liu asked for advice humbly.

Yao Yuan shook his head slightly and said with a smile, "Wrapping will increase the diameter of the brake hose. Although it is more wear-resistant, it will cause extrusion, and the consequences may be more serious. The same is true for welding. There is only one way."

"Fill it back with spot welding and smooth it out with sandpaper."

"Spot welding?" Master Liu's eyes were about to pop out, "Such a thin pipe wall will be worn through at a touch, and spot welding is impossible."

Yao Yuan smiled, "Is there a welding machine?"

"Yes." Master Liu said.

Although the factory is going from bad to worse, the equipment is complete.

"Then please help Master Liu." Yao Yuan said.

Master Liu still wanted to persuade him, but when he thought that he had found out the fault after two efforts, he immediately gave up the idea, and hurriedly called his apprentices to pull the welding machine over.

Yao Yuan learned the skill of electric welding from an eighth-level engineer. He was stationed in a certain shipyard in his previous life, and saw that eighth-level worker hand-weld the important parts of the lng ship!That requires welding technology as precise as welding ballistic missiles!

Although he has only followed him for a few months, it is easy to deal with the problem in front of him.
